works as advertised

Ok, the neck on my used Fender Precision Bass had some truss rod nut issues. Whoever owned the bass before was careless when adjusting the truss rod and had rounded out the 5mm truss rod adjustment socket. I would have to loosen the strings whenever I wanted to adjust the neck because of the stripped socket. Since buying this tool I can now adjust the neck with full string tension on it. Very pleased with this purchase.

Great product; one real annoyance...

This group of 'Gripper' truss-rod wrenches has worked very well for me. Gently tapping the wrench into the truss-rod adjusting-nut with a dead-blow hammer or mallet, really helps 'set' the tool into the nut, to create a solid 'bite' on badly damaged adjusting-nuts.

The only problem with this product, is that none of the wrenches' bright-red handles are marked with their size! Some of them have a tiny, stamped-in label in the steel shaft, such as you would find on a standard Allen wrench, but since the wrenches' steel shafts are hardened, they are jet black, which makes the embossings very difficult to see. To make matters even more amusing, these wrenches are all tapered (a key feature), which makes them a bit more complicated to measure...

So, the first thing you'll be doing, is using a Sharpie (or similar) pen, to label your new collection of wrenches. Otherwise, it's a fine product.
